Alot of men after the age of 40 have to be careful of going on a health kick alot of men die of heart attacks exercising I was watching a heart specialist talk about this on you tube a few years ago and he was saying you have alot of toxins in your body built up and when you start a health kick to aggressively
It's released to fast into your blood which in turn makes your blood thicker and harder to move around the body
He recommended starting with healthy eating for a month then slowly building up the exercise not to much latic aicd release in a short space of time and toxicity for the kidneys to filter
